Thank you for taking the time to report this bug and helping to make
Ubuntu better. It sounds like some part of the system has crashed. To
help us find the cause of the crash please follow these steps:

1. Look in /var/crash for crash files and if found run:
    ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.

2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where
ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine.
Do you find any links to recent problems on that page? If so then please
send the links to us.

3. If step 2 also failed then apply the workaround from bug 994921,
reboot, reproduce the crash, and retry step 1.

Please take care to avoid attaching .crash files to bugs as we are
unable to process them as file attachments. It would also be a security
risk for yourself.

Title:
  System logout when turn off the screen or suspend Ubuntu 18.04

Status in gnome-shell package in Ubuntu:
  Incomplete

Bug description:
  When turn off the screen or suspend, and resume the system is logged
  out, this mostly happens with nvidia driver (390 or 396). I noticed
  that when close the lid and reopen the system is still working and all
  of a sudden it appears a login screen and when login all programs as
  killed as it was logged out. And most of times after login it locks
  and prompts an unlock screen.

  I tried to switch to nouveau driver and the problem seems not to
  happen, but that leaves me with a poor performance in terms of
  graphics.

  I tried to reset the setting in dconf using dconf-editor to reset the
  system recursively, at the beginning seems to be solved but it gets
  back.

  I need to mention that I faced the same problem when using budgie flavor, I 
thought that it might be a budgie problem but it appears to be a gnome problem 
since budgie is based on gnome and on both the problem happens when using 
Nvidia drivers.
